Yes. The Dual-tone Crosstrain styles are listed as Crosstrain Thermal Yoga Pants, made to move comfortably through stretches, flows, and post-class cool-downs.
Absolutely. The clean dual-stripe look pairs easily with 4-rth tanks and zip hoodies, so they shift from studio wear to relaxed, day-to-day outfits.
A lightweight Modal knit made from birch-tree fiber, blended with a touch of Lycra for flexibility and a soft, breathable feel.
They include a custom super-soft waistband and a no-fly front with center stitching, keeping the shape smooth and secure without bulk.
Two dual-tone options: Green & White Stripe and Red & Grey Stripe, both shown on the collection page.
Sizes Small, Medium, Large are listed on the product pages, with a fit guide and inseam chart provided for reference.
The color blocking is part of the knit design; gentle washing in cold water, as noted on product care instructions, helps maintain its look over time.
Shipping & Returns are linked in the site footer, and the banner highlights current U.S. free-shipping eligibility on qualifying orders.
Great color yellow. Just a bright tank top a real head turner
Just about the nicest shorts I've ever owned. Shape, cut, styling, all very cute... not to mention how hard it is to find menswear in the Purple color range. Lovely dark shade of plum, quite soft, comfortable, and stretchy. Also, sizing advice is spot on. Very happy with these shorts.
I have three pairs of these pants and love them. I can move very freely. I also love the fabric being Polyester free and the length is very helpful for providing traction during arm balances.
These are my favorite hot yoga shorts. Super comfortable and allow for great movement.
Finally located my go-to lounge pants. Quality construction, slim profile, characterful touches like the cuff design, ideal fabric weight, stretchy waist, and the major one: the *IDEAL* length to attractively accommodate my 5' 6" frame sans excess fabric... because a dude wants to show some leg, y'know? Love these things. I own them in two colors - cinnabar red & the lovely light cloudy grey, which I prefer to the more common dark charcoal greys. To nitpick, the zippers could be higher quality and not boring black, such as a more substantial YKK with perhaps an aged nickel patina. That is the single attribute that I could envision to be upgraded in a future iteration. Still, I am so pleased with these as everyday lounge/walking pants than I cannot bother reducing a star.
I just ordered 3 more of these after my first 3 I ordered finally had to be discarded after about 4 years of constant use. Best shorts ever and only shorts I buy and wear!
Amazingly comfortable and fantastic customer service
These yoga and workout pants are perfect for me. Comfortable, conforming,and stylish and functional. Nice material and construction. These pants have a lot going for them. The make me happy when I have them on.
I love these sweat pants. They are super comfortable and very well made.
I mainly wear a small when wearing 4-rth clothing. However, I wanted a more loose and casual fit so I got these in a medium for house lounging…. I love them, they are super comfortable and very well made.
Excellent for hot yoga. Very pleased with the fit and performance.
I just received two pairs of the ultra flex and love them! The fit is great and I really love your company!
These cuffed yoga pants are great! I liked them so much I ordered two more.. for reference I am 5’9/160 lbs… the small works great for my frame.
These feel so good to the skin. The fit is correct and they look great. Might be my favorite pair of sweats. I bought 7 more pairs and cant wait to receive them!
These are comfortable and cool all rolled into one. Great for kicking it back at home or any casual event. Yoga. Running. There is no limit.
Absolutely love the fit and feel.
These are hands down the most comfortable and attractive shorts I’ve ever owned. I’ve never gotten as many compliments about an article of clothing before (all from women, fwiw). I have these in three different colors but these seem to get the most positive feedback. I’ve worn them to the beach (even swam in them), to the grocery store, to Pilates. Had to get up my nerve to go all white in public (with no underwear) but it was totally rewarding. They’re the best.
